I've figured out Christopher's "I'm hungry" cry - but I know that by the time he's actually crying for it, he's REALLY hungry. At some point, I should be able to figure out that he's hungry just by his body language, etc - right? When was that point for you (if it's happened

)?
Re: When did you learn your LO's hunger cues?
he is probably rooting before the all out cry: make a baby bird mouth, sticking out tongue, sucking on fists etc..
but they eat so much then, he might just be going from 0-60 without many cues.
